Answer 1

So you don't want a 5 or a 6.

In your previous question like this, you found that in 54 tries each number from 1 to 6 will likely come up 9 times each
Then in your 54 tries, if the 5 or 6 can come up 18 times, what are you left with for the other possibility?

Answer 2

what is the theoretical probability that a number less then 5 will be rolled in a number cube
